Before you install
- macOS 14 Sonoma or later — earlier systems aren't supported.
- Apple Silicon or Intel — one universal build covers both.
- Full-disk access by grant — on first scan, macOS asks you to grant folder access; the grant persists securely across relaunches.
Frequently asked questions
Which macOS versions are supported?
NullDisk requires macOS 14 (Sonoma) or later, on both Apple Silicon and Intel Macs.
Where do I download NullDisk?
The Download button above gives you the current notarized build straight from nulldisk.app, and the Mac App Store is coming. Always download from those official sources — never from aggregator sites.
What is NullDisk’s licensing model?
The direct-edition license permits free personal and workplace use, with no expiry. Every app feature is included. An optional one-time license removes reminders permanently; it does not unlock features. See the pricing page for license details.
How do I get help?
Email support@nulldisk.app with your macOS version and what you were doing and we will get back to you.
